Parameter Comparison

Engineering Selection Recommendations

Primary Selection - Amphenol RF 172142HEX: The main part remains the optimal choice for applications where the specified operating temperature range of -40°C to 140°C and 100 mating cycles are sufficient. This part carries ROHS3 compliance and maintains Active product status with robust inventory availability.

Substitute Selection - Amphenol RF 82-5370: This substitute offers extended operating temperature range (-65°C to 165°C) and increased mating cycle rating (500 cycles) compared to the main part. The 82-5370 maintains ROHS3 compliance and is manufactured by the same supplier as the main part. This option is suitable for applications requiring enhanced thermal performance or higher mechanical durability. Inventory availability is 832 pieces.

Substitute Selection - Cinch Connectivity Solutions Johnson 138-4408-007: This substitute provides equivalent electrical and mechanical specifications with extended operating temperature range (-65°C to 165°C) and increased mating cycle rating (500 cycles). The part carries RoHS compliance and is suitable for applications requiring cross-manufacturer sourcing or supply chain diversification. Inventory availability is 781 pieces.

All three parts satisfy the core electrical requirements for 50 Ohm N Type RF coaxial connector applications operating at frequencies up to 11 GHz with RG-55, RG-142, RG-223, and RG-400 cable compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 82-5370 or 138-4408-007 be used as direct replacements for the 172142HEX in existing designs?

A: Yes. Both substitute parts match all critical electrical and mechanical parameters: N Type connector style, 50 Ohm impedance, 11 GHz maximum frequency, free hanging in-line mounting, threaded fastening, crimp or solder center contact termination, and crimp shield termination. Cable group compatibility (RG-55, 142, 223, 400) is identical across all three parts.

Q: What are the differences between the three parts?

A: The primary differences are operating temperature range, mating cycle rating, body finish material, and voltage rating. The 172142HEX operates from -40°C to 140°C with 100 mating cycles. Both substitutes extend the operating range to -65°C to 165°C and support 500 mating cycles. Body finish varies: White Bronze (172142HEX), Nickel (82-5370), and Tri-Alloy (138-4408-007). Voltage ratings are not specified for the main part, 1500 V for the 82-5370, and 335 V for the 138-4408-007.

Q: Are there any compliance or regulatory differences?

A: The 172142HEX and 82-5370 both carry ROHS3 compliance. The 138-4408-007 carries RoHS compliance. All three parts are classified under ECCN EAR99 and HTSUS 8536.69.4010. The 172142HEX and 82-5370 are REACH Affected; REACH status for the 138-4408-007 is not specified in the provided data.

Q: Which substitute should be selected for high-temperature applications?

A: Both the 82-5370 and 138-4408-007 support extended operating temperatures from -65°C to 165°C, compared to the main part's -40°C to 140°C range. Either substitute is suitable for high-temperature applications within these limits.

Q: What is the insertion loss specification?

A: The main part 172142HEX does not specify insertion loss. Both substitutes (82-5370 and 138-4408-007) specify 0.15 dB insertion loss at the operating frequency.

Q: Are the packaging and included components identical?

A: All three parts are supplied in Bulk packaging. The 172142HEX and 82-5370 include 3 pieces: 1 Connector, 1 Contact, and 1 Ferrule. The 138-4408-007 includes 3 pieces: 1 Connector, 1 Contact, and 1 Sleeve. The functional equivalence of Ferrule versus Sleeve for the intended application must be confirmed in the specific cable assembly design.

Q: What inventory levels are available?

A: Current inventory levels are 1057 pieces for the 172142HEX, 832 pieces for the 82-5370, and 781 pieces for the 138-4408-007. All parts are listed as New Original In Stock.
